MSP430: Don't override default ISA when MCU name is unrecognized
430X is the default ISA under normal operation, so even when the MCU name
passed to -mmcu= is unrecognized, it should not be overriden.
gcc/ChangeLog:
* config/msp430/msp430.c (msp430_option_override): Don't set the
ISA to 430 when the MCU is unrecognized.
gcc/testsuite/ChangeLog:
* gcc.target/msp430/430x-default-isa.c: New test.
